By using the following program, you can quickly display the index tags available for the current database, rather than making the user open the View window and then the database setup.

   CLEAR
   x=1   && used for both tag counter and screen coordinate counter
   IF LEN(TAG(DBF()+".cdx",1))>0
     @x+3,2  SAY "Tag Name"
     @x+3,22 SAY "Index Expression"
     DO WHILE LEN(TAG(DBF()+".cdx",x))>0
       SET ORDER TO ALLTRIM(TAG(DBF()+".cdx",x))
       @x+5,2  SAY TAG(DBF()+".cdx",x)
       @x+5,22 SAY IIF("DESCENDING"$UPPER(SET("ORDER")),"Dsc", "Asc")
       @x+5,27 SAY KEY(DBF()+".cdx",x)      && SAME AS SYS(14,x,DBF())
       x=x+1
     ENDDO
   ELSE
       @2,2 SAY "No tags defined."
   ENDIF
   RELEASE x
